Introduction: Internet interventions are effective in reducing alcohol consumption among college students, but studies have high dropout rates. Identifying the factors associated with adherence may help the development and enhance the effects of these interventions. Objective: To examine the association between student characteristics and recruitment strategies on enrollment in a web-based intervention for alcohol use among college students. Methods: A total of 46,329 university students aged between 18 to 30 from all regions of Brazil who reported alcohol consumption in the last three months participated in the research. Three recruitment strategies were used: open invitation without incentive published on a website, invitation without incentive directed to the student or with an incentive (school credits). Students were followed after 1, 3 and 6 months and the questionnaire evaluated educational, sociodemographic characteristics, motivation level and alcohol use. Statistical analyzes considered logistic regression models and a minimum significance level of 5%. Results: Women (aOR = 1.09 95% CI: 1.04; 1.14 p = 0.001) and higher income students (aOR = 1.32 95% CI: 1.21; 1.45 p<0,001) were more adherent, as well as more motivated students (aOR = 1.04 95% CI: 1.03; 1.05 p<0,001). Adherence was also higher among college students who reported binge drinking (aOR = 1.26 95% CI: 1.19; 1.33 p<0,001) and with risk alcohol use (aOR = 1.11 95% CI: 1.05; 1, 18 p<0,001). The number of negative consequences related to alcohol use was not associated with adherence (aOR = 0.99 95% CI: 0.98; 1.00 p = 0.117). Recruitment using incentives (school credits) increased adherence nearly four times (aOR = 3.97 95% CI: 2.65; 5.95 p<0,001). Conclusion: The use of incentive was the main factor associated with adherence. Sociodemographic, alcohol use and motivational characteristics were also associated with the adherence rates to the intervention. The results may help the development of future interventions for alcohol use via internet.
